Consciousness is a complex and multifaceted concept that refers to our subjective experience of the world and ourselves. It is the state of being aware of and able to perceive both external stimuli (such as sights and sounds) and internal mental processes (such as thoughts and emotions).
The nature of consciousness is a topic of ongoing scientific and philosophical inquiry. While there is still much we don't fully understand about consciousness, it is generally believed to emerge from the interactions of various neural processes in the brain.
Regarding your second question, yes, it is possible to become aware of our own consciousness even when there are no thoughts or memories involved. This state is often referred to as "pure awareness" or "consciousness without content." It is a form of mindfulness or meditation where one directs their attention inward, observing their own consciousness without being entangled in specific thoughts or memories.
During such moments of pure awareness, individuals may experience a sense of clarity, presence, or heightened self-awareness. It's like being aware of the "awareness" itself, without getting caught up in the usual stream of thoughts and mental chatter. Some practitioners describe it as a state of profound stillness and peace.
Meditation and mindfulness practices are often used to cultivate this kind of awareness. By learning to observe the mind without getting swept away by its contents, individuals can gain insight into the nature of consciousness and experience a deeper sense of self.
Experiencing consciousness without thought or memory can be challenging, as our minds are accustomed to being constantly engaged with thoughts and perceptions. But with regular practice and patience, it is possible to touch these moments of pure awareness and glimpse the essence of consciousness itself.
